In chronic kidney disease, the falling glomerular filtration rate leads to more and more renin secretion which leads to hypertension.

慢性肾病中，GFR降低，导致更多肾素分泌，进而引发高血压。

Now, acute kidney injury can cause a low glomerular filtration rate, which is the volume of blood filtered through the kidney over a period of time, and this can lead to oliguria and hyperkalemia.

严重的肾损伤可以降低肾小球滤过率，即单位时间内肾脏过滤的血液量，这可以导致少尿和高钾血症。
